I looked at it and concluded that our FFTs are on the whole too short for it to be worthwhile, and a lot of calculations aren't FFT bound anyway. An awful lot of our stuff is simply not very slow. Also, GPU computing at the moment is crippled for many problems by the bandwidth bottleneck and multitasking limitations. Both of those problems will go away with GPU features integrated onto the CPU. At that point the level of work required to implement it will drop significantly, and the range of application of the technology will increase significantly. So I'm waiting for now.
